That ECJ ruling means individuals can request the removal of old and out of date links that are not in the public interest from web search engine results pages.

Google responded by appointing a committee of five "independent" advisors, two of whom have already called for the law to be changed.

In response to Google's prickly response, the European working party – a body which is independent of the EC and represents states' data-protection authorities – promised [PDF] to develop "a coordinated response to complaints of data subjects if search engines do not erase their content whose removal has been requested".

If you don't respect the law, the working party is saying, we'll investigate – and take the side of the individual, where merited. It's about as strongly worded as a communique from a Brussels advisory structure can get.

The Article 29 Working Party (WP29) also advises web search engines "to put in place user-friendly and pedagogical tools for the exercise by their users of their right to request the deletion of the search results links containing information relating to them. More generally, search engines should ensure compliance with the opinion of the WP29 on data protection issues related to search engines".

The working party conclude its latest missive, dated 6 June, by reminding Google that the dispute is part of a "wider context of ongoing exchanges" between Europe's privacy regulators and Google. What this means is a reminder that US-based consumer data-processing giants like Google and Facebook may actually be in breach of European law. ®
